OPERATING INSTRUCTIONS 

 

INTRODUCTION 

 

Based on the long-established and reliable OTF/AS cryostat, the new OTF5000 brings Bright 
cryostats completely up to date. New styling with improved user ergonomics, the latest blade 
systems in the ever-reliable and powerful 5040 microtome, a huge choice of options plus 
money-saving package deals make these cryostats absolutely unique. 
 
They  are  suitable  for  an  endless  range  of  applications  and  in  the  correct  configuration  are 
capable  of  cutting  a  wide  diversity  of  specimens  from  undecalcified  bone  to  brain,  resins, 
plastics and plant tissue as well as more usual soft tissue. Allowing full anti-roll plate adjustment 
for  perfect  results  coupled  with  long  lasting  temperature  stability,  the  OTF5000  can  truly  be 
described as complete.

SWITCHING ON 

 
On  receipt  of  your  new  Bright  instrument,  please  refer  to  the  Receipt  and  Unpacking  section 
and the Assembly and Installation section of this Handbook 
As part of its policy of continual improvement, Bright Instrument Company Limited reserves the 
right to incorporate changes, or make additions to, without prior notice. There may, therefore, be 
minor  detail  differences  between  the  information  in  this  manual  and  your  instrument.  These 
differences will not affect the safety and use of the instrument. 
After settling, switch on the  power (see section 2.1.1). Initially the LED displays will flash for  a 
few  seconds.  Once  the  displays  are  constant,  the  required  chamber  temperature  can  be  set 
(see  section  2.1.8).  After  the  cryostat  has  reached  the  set  chamber  temperature,  leave  for  a 
further two hours before attempting to cut sections.
